Admin & Display: you're now able to share reviews across products. This is helpful for when you have one product with multiple listings, such as a subscription vs one-time purchase product.
Display: reviews now show a link to the product that was reviewed when they appear anywhere other than the product page itself. Most commonly, on the dedicated reviews page.
Forms: we released post submission actions, starting with requesting store reviews after completing a product review form.
Admin: filtering by star rating is now possible in moderation.
Forms: review titles are now pre-filled from the review content when a customer is submitting a review. Customers can skip this step now, or choose to submit a unique title.
